AbstractAbstract

[en] Levels in ¹⁵²Ce are identified for the first time along with new high spin states in ^142-148Ba, ^144-150Ce and ^150-156Nd from X-X, gamma -X and gamma - gamma - gamma -ray coincidence measurement in spontaneous fission of ²⁵²Cf and ²⁴²Pu. The N=88, 90 Ba nuclei have very nearly identical J₁ for the yrast bands (2⁺ to 10⁺) and for the octupole bands (3^- to 15^-). The N=92, 94 Nd nuclei have essentially identical yrast J₁ (0⁺ to 16⁺).
